SOAP-BUBBLE DEVICE.

Specification of Letters Patent.

- Patented May 18, 1920.

Application filed September 8, 1919. Serial No. 322,287.

To all whom it may concern:

Be it known that I, MICHAEL G. DOBBINS, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Soap-Bubble Devices, of which the following is a specification.

The invention relates to games and toys and has for an object to provide a device for producing and blowing soap-bubbles.

Among other features the invention comprehends a device that may be commonly termed a-soap-bubble pipe and which provides a reservoir or a chamber for a quantity of liquid soap, an outlet from the chamber with means for blowing a quantity of air into the chamber and through the outlet to form the bubble and means for forming a film or surface of the soapy solution which ultimately forms the bubble. Still further the invention comprehends a soap-bubble pipe which need not be dipped into the soapbubble solution each time that it is desired to blow a bubble, the device in this respect being self-contained in that one filling of solution in the pipe provides for the blowing of numerous bubbles with great rapidity and with very little effort on the part of the operator.

In the further disclosure of the invention, reference is to be had to the accompanying drawings, constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which,

Figure 1 is a side elevation of the device showing same in use.

Fig. 2- is a vertical sectional view taken through the pipe, the stem however being shown partially inside elevation with the dotted lines indicating different positions of the wiper or film producing element.

Fig. 3 is a vertical transverse sectional view taken through the structure shown in Fig. 2, and, I

Fig. 4- is a horizontal sectional view taken on the line 4- 1 in Fig. 2.

Referring more particularly to the views I provide a casing 10 forming a chamber 1]., the casing having a suitable cover 12 supporting a tubular stem 18 which extends into the chamber and through which air is blown for the purpose of forming a soap-bubble and around the mouth 16.

The film producing element 18 is provided and consists of a substantially inverted- U-shaped holder 19 for a wiper 20, the latter being preferably formed of a flat piece of rubber or some other resilient material with the holder 19 having indented portions 21 at the points where the holder passes through the cover, the upper portion of the holder lying exteriorly of the casing so that it can be operated with the finger as shown in Fig. 1.

Normally the wiper lies in thesoap solution 17 as shown in dotted lines in Fig. 2, and in the operation of the device the operator imparts a swinging movement to the holder 19 by pressing against the exterior projecting portion thereof, thus swinging the holder and causing the wiper to be removed from the solution and drawn across the inner end of the mouth 16, said operation resulting in the formation of a film of soap solution across the inner end of the mouth with the wiper adapted to again be immersed in the solution on the opposite side of the chamber upon continued movement of the holder so that the wiper will receive a new covering or coating of the solution subsequently to be deposited across the inner end of the mouth when the wiper is reoiprocated to be returned to its initial position. as initially described. After the wiper has been drawn across the inner end of the mouth to form a film of soap solution thereon, the operator blows through the stem 13 thus resulting in a pressure of air in the chamber 11, which air forced outwardly through the mouth, will expand the soap film into the bubble 14:. A slight quick movement of the bowl or casing 10 will cause the complete bubble to be released from the mouth and then upon operating the wiper, produces another film of soap solution, and it will be apparent that the device will be ready to bring about the formation of a new bubble by repeating the heretofore described operation.

From the foregoing description it will be apparent that the device described is of a simple construction; consists of few parts that cannot readily get out of order; the entire structure is practically self-contained in that the bowl forms a reservoir for a con siderable quantity of soap solution and that the device can be operated with very little experience and in fact by persons not skilled in the art oi blowing soap-bubbles.

Havingde'scrib'e'd my invention, I claim- 1. A device of the character described comprising in combination with a fluid-con mining receptacle having an outlet forming ain'outh, of reciprocatingly mounted means for contact with the fluid of the rec'eptacie and movable to be drawn acrossthe mouth to form a film of the fluid thereon 2. A device of the character described comprising in combination with a fluid-containi-ng receptacle having anoutlet forming a mouth, of a reciprocatingly mounted wiper disposed tocontact with the fluid in the receptacle and a wiper mounted to swing on the cover and extending into the recepta'cle for contact with the fluid therein, said wiper being adapted to be moved across an outlet of the receptacle to form a' film of fluid across said outlet. 7

In testimony whereof I aflix m signature.
